Ascience teacher, an art instructor, and a religious studies teacher are arguing about their respective disciplines. which of the following could be a claim that each teacher makes?

You didn't give us any choices, and we don't always understand what
"the following" means any better than you do, so I can't help you select
the best one from the list.

The only way I can answer this question and legitimately take your
points is to make up a claim.  So here's the one I just invented:

"The quality of work in MY discipline can't be judged or evaluated
using the standards and principles of YOUR disciplines."
